[有趣]流星雨(Meteor Shower)

昨天超期待可以看到流星雨的(8/12-8/13,2007。)

The comet Swift-Tuttle orbits the Sun with a period of about 130 years. Whenever the comet comes close to the Sun in its orbit, it ejects a stream of dust particles, which are then distributed along its orbit. When the Earth passes through their path - a regular occurrence every August - we see a meteor shower, a fabulous spectacle for viewers on Earth. The last such ejection from Swift-Tuttle took place in 1992.

聽說晚上九點到十點左右開始有流星雨，凌晨兩點最大值，我十點左右在窗邊看，發現外面燈光太亮，本來還天真地想說晚點會不會大家都熄燈，就可以看到，後來有人提醒，天空連一顆星星都看不到了，怎麼可能看到流星雨...啊，想當初露營的時候，滿天繁星，如果流星雨是那個時候就好囉。

不過，很快又有機會可以看到流星雨：The next scientifically interesting meteor display coming up is the Aurigid shower, a once-in-a-lifetime show originating from a long-period comet taking about 2000 years for each of its orbits around the Sun. The meteors from this comet reach us only every 70 years. It is expected to be visible from North America, Mexico, and Hawaii, with its peak on the morning of 3 September 2007.

後來又聽說這禮拜都可以看到，所以昨天晚上趴在鋼琴上等流星，疑似看到三四顆，為什麼用疑似呢？因為流星消失很快，有種好像看到又像沒看到的感覺，尤其是早上醒過來後，更像是在作夢...
